Aurora U. ★★★★★

The black oxide finish is a nice touch—these threads slid into my jig plate without any galling, and the 12.9 hardness gives me confidence they’ll hold up under repeated torque. They seat flush nicely with the hex drive, and the 25-pack means I have spares for the next project.

Sofia L. ★★★★★

The hex socket drive on these M16 screws lets me torque them down accurately without stripping, and the black oxide finish holds up well in my jig setup. Fit perfectly into existing tapped holes with no binding.

Jacob G. ★★★★★

Had to pull these out for a jig rebuild on a heavy press, and the black oxide finish handled the oil and grime without any rust starting. The hex drive engaged cleanly even with a worn allen key, which saved me a trip back to the toolbox. Good, solid fit for M16 threaded holes.
